The metal-rich globular clusters of the Milky Way.

HEITSCH F. and RICHTLER T.

Abstract (from CDS):

We present new (V,V-I)-photometry of the metal-rich globular clusters NGC 5927, NGC 6316, NGC 6342, NGC 6441 and NGC 6760. The clusters show differential reddening up to δEV–I=0.32mag, for which the CMDs are corrected via extinction maps. There are hints of a variation in the extinction law. Two different ways to determine the parameters metallicity, reddening and distance lead to consistent results. The metallicities of the clusters range between -0.7≤[M/H]≤0.0dex and the absolute reddening between 0.43≤EV–I≤0.76mag. Taking the differential reddening into account leads to slightly increased distances. From the resulting parameters we conclude that the usual halo-disk-distinction in the system of globular clusters seems questionable.
